HEAT DISTRIBUTOR.

Application filed June 4, 1925.

My invention relates to improvements in heat distributors, and it consists in the combinations, constructions, and arrangements herein described, and claimed.

An object of my invention is to provide a heat distributor of the character described which is intended for disposition over a gas burner or over the lid opening of a coal stove, in which particularly novel means is employed for distributing heated air between. the distributor and a kettle, pot or pan placed thereon so as to convey the maximum amount of heat from the distributor to the kettle, pot'or pan.

A further object of my invention is to provide a heat distributor of the character described having a reversible handle member which may be turned 180 at will so that the top surface or bottom surface of the distributor may be exposed to the gas burner or flames of the coal or wood stove, as desired.

A further object of my invention is to provide a heat distributor of the character described in which particularly novel means is employed for supporting the handle mem ber upon the body portion of the distributor.

A further object of my invention is to provide a heat distributor of the character described which is simple in construction, durable and thoroughly efficient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application, in which- Figure 1 is a top plan view of an embodiment of my invention,

Figure 2 is a side elevation of the mecha nism illustrated in Figure 1,

l igure 3 is a. sectional view along the line 23-3 of Fig. 1. and

. Figure 4- is a sectional view along the line l-l of Figure 1.

In carrying out my invention I make use of a sheet metal body member 1 having the form of a disc. The body portion 1 has-a plurality of involute embossed portions 3 at a point adjacent to the center of'the body member and extending to points adjacent to the periphery of the body member. The height of the involute embossed portions 3 is uniform throughout (see Figure 8) Serial No. 34,964.

A substantially annular wire member 4 is disposed concentric with the peripheral edge of the member 1 and a portion 5 of the memher is crimped around the wire as shown in Figure 3. g

The member 4 has a portion 6 substan tially loop-shaped extending laterally therefrom. This portion 6 serves as a means for supporting a handle member. The handle member consists in a loop-shaped wire 7 which is disposed in longitudinal alignment with the portion 6 and with its ends astride the portion 6 as shown in Figure 1.

The outermost ends of the looped handle member 7 extend laterally therefrom as shown at 8, one On either side of the parallel portions of the portion 6.

A pair 'of metal rings 9 encompass the 'portion 6 of the member 4 and are soldered thereto, one on either side of the laterally extending ends of the handle 7. Thus the handle 7 may not be moved longitudinally with respect to the portion 6. A third wire ring 10,' substantially elliptical in contour and identical to the rings 9 is disposed upon the portion 6 and soldered thereto adjacent to the outermost end.

The handle 7 is of resilient wire and as reference to Figure 2 will show is curved at- 11 so as to curve upwardly when in the position shown in Figure 2.

If now the handle member 7 is rotated in a counter clockwise direction (see Figure 4) the end portions thereof will cross one another as shown indotted lines, and the handle will turn over and assume the position shown in dotted lines of Fig. 2 without twisting the wires of the handle. The handle will retain this position until again manually turned in a clockwise direction.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. In employing my improved heat distributor I place the distributor over a gas burner or opening in a coal or wood stove, the lid having first been removed.

A pot, kettle or pan is placed upon the involute portions 3 and the portion 2 which face upwardly and heat from the burner or fire heats the body member 1.

The hot body member 1 and involute port-ions 3 serve as radiating surfaces which heat the air between the pot, kettle or pan, and the body member. This air in escaping must pass over a relatively long path because of the contour of the involute portions 3 and thus a maximum quantity of heat is conducted to the bottom of the utensil placed upon the device.

It will thus be seen that I have provided a device which may be used on both sides and in which the relative position of the handle will be the same Whether used on one side or the other.

Furthermore that in either position the handle Will firmly hold the device Without any danger of its reversing. This is due to the fact that when the wires cross each other as already described, a certain amount of force is necessary. This force can be readily applied by manually rotating the handle but is sufficient to prevent the accidental reversal of the parts, 7 7

At this time the handle is in the position shown in full lines of Figure 2.

If new it is desired to reverse the body member, and use the body memberas the lid of a stove or as a baking pan, such as a griddle, the handle member 7 is rotated in a counter clockwise direction upon its axis which permits the adjacent and parallel portions of the handle member Within the rings 9 and 10 to cross one another, as shown in dotted lines in Figure l, and to assume the position shown in the figure.

I claim:

,1. A heat distributor of the character described comprising a metal body member havinginvolute embossed portions extending from points near the center thereof to a point adjacent to the peripheral edges, the oppositeside of the metal body member being substantially flat, a handle secured to said member; and means forpermit-ting the rotation of the handle With respect to the body portion for 180 and for retaining it in its rotated position. 7

A heat distributor of the character described comprising a metal body member haying involute embossed portions extending from points near the center thereof to a point adjacent to the peripheral edges, the opposite side of the metal body member being substantially flat, a Wire handle rot-atably secured to said body portion and means associated with, said Wire handle for permitting the revolution of the Wire handle for 180 and for holding the Wire portions in relatively the same position as before rotation.

3. A heat distributor of the character described comprising a substantially flat sheet metal body member having involute em-- bossed portions extending from points near the center thereof to a point adjacent to the peripheral edges, an annular Wire member secured to the body member at the peripheral edges thereof and having a loop-shaped extensiom a loop-shaped Wire handle having its inner edges bent laterally, one of said laterally bent edges extending above said looped extension and the other below it, and elliptical-shaped retaining rings enclosing said loop-shaped extension and portion of said handle.

a. A heat distributor of the character described comprising a substantially flat sheet metal body member having involute embossed portions extending from points near the center thereof to a point adj acentto the peripheral edges, an annular wire member secured to the body member at the peripheral edges thereof and having a loop-shaped ex-' tension, a loop-shaped Wire handle having its inner edges bent'laterally, one of said laterally bent edges extending above said looped extension and the other below it, and elliptical-shaped retaining rings enclosing said loop-shaped extension and portion of said handle, and said loop being disposed on each side of said laterally extemling end portions.
